handle machines, tools, or extension cords. Always lock up tools and keep out of reach of
Use the right tool for the job. This product should not be used for fluid transfer into aircraft.
This product is not suited for use with fluids for human consumption or fluids containing water.
Do not modify this tool and do not use this tool for a purpose for which it was not intended. It
will do the job better and more safely at the rate for which it was intended.
Do not overreach. Keep proper footing and balance always. Do not reach over or across
running machines.
Maintain tools with care. Follow instructions for lubricating and changing accessories. Inspect
tool cords periodically and, if damaged, have them repaired by an authorized technician. The
handles must be kept clean, dry, and free from oil and grease always.
Stay alert. Watch what you are doing, use common sense. Do not operate any tool when you
are tired.
Check for damaged parts. Before using any tool, any part that appears damaged should be
carefully checked to determine that it would operate properly and perform its intended function.
Check for any broken parts or mounting fixtures and any other condition that may affect proper
operation. Any part that is damaged should be properly repaired or replaced by a qualified
Replacement parts and accessories. When servicing, use only identical replacement parts.
Use of any other parts will void the warranty. Only use accessories intended for use with this
Do not operate tool if under the influence of alcohol or drugs. Read warning labels when
taking prescription medicine your judgment or reflexes may be impaired. If there is any doubt,
do not operate the tool.
Pacemaker safety warning. People with pacemakers should consult with their physician(s)
before using this product; operation of equipment near a heart pacemaker could cause
interference or failure of the pacemaker.
Pump has a built-in check valve with pressure relief to prevent fluid thermal expansion from
causing unsafe system pressures. Do not install additional check valves or foot valves during
installation without proper pressure relief valves built into them. Housing or plumbing cracking
may result.
The warnings, cautions, and instructions discussed in this instruction manual
cannot cover all possible conditions and situations that may occur.
It must be understood by the operator that COMMON SENSE AND CAUTION
• Disconnect power to pump before servicing pump.
• To keep pump running at its best, thoroughly flush pumps to be stored for long periods of time with
diesel fuel.
• Remove and clean strainer screen after every 20 hours of operation. Cleaning frequency depends
on fluids being pumped.
• For your safety, service and maintenance should be performed regularly by a qualified technician.
• Take motors needing service to an authorized repair shop to maintain “explosion proof’ integrity.
• The hose used with this pump must be of conductive jacket design, or have ground wire connecting
inlet and outlet fittings to avoid build-up of static charge.
• Systems should be set-up to require a minimum amount of suction lift. Maximum vertical distance
from the surface of the fluid in the tank to the inlet of the pump is 9 ft. for gas and 10 ft. for diesel
• A filter should be used on pump outlet to ensure that no foreign material is transferred to fuel tank.
• Tank or barrel must be properly vented.
• Use a gasoline and oil proof pipe compound on all joints.
• A water separator should be used for pumping diesel fuel.
1. Tightly screw extension pipe into inlet flange of pumping unit. Attach second extension pipe and
suction pipe to extension pipe in the same manner.
2. Cut suction pipe to a length that will place its end within 3” of the BOTTOM of the tank. Do not rest
suction pipe on bottom of tank.
3. Screw inlet flange of pump into tank or barrel opening inlet flange must be completely and securely
threaded into an undamaged tank or barrel bung.
4. Install hose and nozzle to pump before connecting power wires together. Ground wire must be
5. Tank or barrel should be anchored down to prevent tipping when full or empty.
If Connected to A Vehicle:
1. DO NOT attempt to power the pump from thin vehicle wiring such as the cigarette lighter wire.
2. Ground wire must always be independently connected to chassis of vehicle being fueled and/or
container being filled. DO NOT connect green and black wires together, for example.
3. Unless pump body and tank/chassis are at same electrical potential, sparking due to static charge or
wiring faults could ignite fuel fumes, resulting in an explosion.
4. If pump is to be powered from a vehicle power system, it is recommended that permanent wiring
and connections be made to vehicle power system which includes a 30-amp slow blow fuse.
Read and understand all the electrical wiring instructions before proceeding.
Remove pump’s electrical junction box cover and straighten the 3 wires to make the stripped wire
ends accessible outside of the junction box.
2. Screw furnished cable connector in to the conduit opening in pump junction box.
3. Strip 6 inches of the outer insulating covering from one end of the furnished electrical cable being
careful not to damage the wire insulation.
4. Pass the stripped end of the furnished cable through the cable connector until 2 inches of the
unstripped wire is within the junction box.
5. Strip 1 /2 inch of the insulation from the ends of the cable wires. Connect these wires to the matching
colored pump wires using wire nuts, be sure no bare wire is exposed.
6. Fold wires into junction box and replace cover.
7. Make sure all screws are seated so there is no space between the cover and the junction box.
8. Run the electrical cable to the vehicle power system, supporting the cable as necessary and
protecting it from sharp edges, heat and anything that could damage the cable.
9. Strip the outer cable covering as necessary. Make a solid electrical connection to the vehicle frame
with the ground (green) wire.
10. To determine if the vehicle electrical system is negative (-) or positive (+) ground, check the battery
marking of the terminal that is wired to the vehicle frame or motor block. For vehicles with negative
ground, connect the negative (black) to the vehicle frame. For vehicles with positive ground, connect
the positive (red) wire to the vehicle frame.
11. Attach one end a 30-amp fuse holder to the end of the remaining wire. Connect the other end of the
fuse holder to the ungrounded side of the power source. The battery terminal or the end of the
battery cable is recommended.
12. Check all connections to make sure they are correct. Install the 30-amp slow blow fuse in the fuse
The installation is now complete.
To ensure ultimate performance, pump must be set up per INSTALLATION section of this manual. On
initial start-up, it may be necessary to hold nozzle open a few seconds to allow pump to prime:
Remove nozzle from pump and insert into tank.
Turn pump on by lifting the switch lever.
Begin fueling by squeezing nozzle lever.
WARNING! The pump motor is equipped with thermal with thermal overload protection. If overheated, it
will shut itself off without any damage to the windings. Be sure to turn off the pump power if this occurs. As
the motor cools, it will start without warning if power is on.
